<?php $doc = new DOMDocument(); $doc->load( 'books.xml' ); $books = $doc->getElementsByTagName( "book" ); foreach( $books as $book ) { $authors = $book->getElementsByTagName( "author" ); $author = $authors->item(0)->nodeValue; $publishers = $book->getElementsByTagName( "publisher" ); $publisher = $publishers->item(0)->nodeValue; $titles = $book->getElementsByTagName( "title" ); $title = $titles->item(0)->nodeValue; echo "$title - $author - $publisher/n"; }?>
